The filter is a direct form II transposed implementation of the standard difference equation (see Notes). The function sosfilt (and filter design using output='sos') should be preferred over lfilter for most filtering tasks, as second-order sections have fewer numerical problems. WebFigure 12. 2-pole, multiple-feedback (MFB), low-pass filter. The multiple-feedback filter inverts the phase of the signal. This is equivalent to adding 180° to the phase shift of the filter itself. The variation of phase vs. frequency is shown in Figure 4 (right axis). This will be referred to as the inverted, second-order, low-pass response ... bluetooth 2 way speaker
